摘要
利用MATLAB语言对一个五层框架进行动力时程分析,给出了该多自由度体系的动力响应并用图表形式直观显示,及通过SAP2000分析软件对计算结果进行验算比较。结果表明,利用MATLAB语言可以高效地对多自由度体系运动方程进行分析运算,得到较为精确的计算结果。同时对设计人员计算多自由度系统的结构动力特性提供了参考依据。
This paper uses the MATLAB language to analysis a five-story frame by seismic waves to give the dynamic response of the system of multi-degree of freedom and to make the chart to show it directly as well as to check the results through the analysis of SAP2000. The results show that using the MATLAB language can do more efficient calculation and analysis of the multi-degrce of freedom system of equations of motion and get more accurate results. At the same time, it can provide the reference to designers to calculate the natural frequency and dynamic characteristics of the complex multi-degree of freedom system.
